The aim of this study is to elucidate the anatomical and functional relationship between dermocartilagenous ligament and depressor septi nasi muscle. The noses of four Korean adult cadavers were studied and total of 123 patients (96 women, 27 men) were operated. The Depressor septi nasi muscle inserted to the base and lateral surface of the medial crus of lower alar cartilage. Dermocartilagenous ligament extended posteriorly and met depressor septi nasi muscle. It was pulled downward by the depressor septi nasi muscle. In all 123 cases the nasal tips were elevated after the dermocartilagenous ligaments were severed. Nasolabial angles increased from 5 - 15 degrees and the noses were shortened. Our morphological study and clinical experience suggest strongly the dermocatilagenous ligament was pulled downward by the depressor septi nasal muscle. We believe the dermocatilagenous ligament acts as a depressor.
本研究的目的是阐明皮肤软骨韧带与降鼻中隔肌之间的解剖学和功能关系。对4具韩国成年尸体的鼻子进行了研究，并对总共123例患者（96名女性，27名男性）进行了手术。降鼻中隔肌插入下鼻翼软骨内侧脚的基部和外侧面。皮肤软骨韧带向后延伸并与降鼻中隔肌相交。它被降鼻中隔肌向下牵拉。在所有123例病例中，切断皮肤软骨韧带后鼻尖抬高。鼻唇角增加了5至15度，鼻子缩短。我们的形态学研究和临床经验强烈表明，皮肤软骨韧带被降鼻中隔肌向下牵拉。我们认为皮肤软骨韧带起到了下压作用。
